Case study

Dragon Ball Z: The Legacy of Goku — a byte-exact GBA disassembly

This project disassembles code from the USA Game Boy Advance release of Dragon Ball Z: The Legacy of Goku into ARM and Thumb assembly and reports a byte-identical ROM rebuild using data from the user's own copy. Build scripts generate assembly for identified code, rebuild compressed streams and compare the resulting image digest with the retail ROM. The author reports that much of the image is source-generated while remaining bytes come from local ROM slices.
